As far as I know, Patrick, the area already purchased by the Spix people for eventual reintroduction is the same area where the last wild bird lived- a farm adjacent to the 'Melancia Creek' . It is just about the only bit of relatively typical Spix habitat left- it has those mature Cariba(?)trees which they feed on, growing along a semi- dry river bed. I believe there's only one other smaller section of habitat somewhere nearby.
I guess the Powerlines are a real danger- especially to newly released and inexperienced birds- they probably can get around this by having markers of some sort on them to make them visible to flying birds- I believe they did that already but(typicallly) they weren't on that section that the female Spix flew into....
Hopefully there'll be news in future of the construction of proper release aviaries etc, I know they did a trial release some years back of captive bred Illiger's macaws in exactly that area (probably using the same aviary the Spix were held in) and exactly along the lines you describe- the birds returning for food etc initially and gradually ranging further away. It did work, apart from one or two that died early on.
With Spix I still feel its quite a long way of. What do you think is the minimum number of captive birds they need to reach as security? Getting ahead of the situation rather but how many do you think they should try eventually for a first release? I really think they are going to be able to pull this species 'back from the brink' now. The darkest days were when there were only about thirty birds, all with private breeders, no cooperation, lots of secrecy and no aim of reintroduction at all. I hope that's all long past now.
